The Kansas forward apparently used Twitter on Saturday to question the talent level of the Washington star. Jackson’s barb came just days before the 2017 NBA Draft, in which most expect the Philadelphia 76ers to select Fultz with the No. 1 overall pick (once they acquire it from the Boston Celtics).

Jackson has since deleted the Tweet, but USA TODAY’s Andrew Joseph captured it in a screenshot.

Fultz shined for the Huskies last season, but his team couldn’t say the same. Washington went a lowly 9-22 and missed the NCAA Tournament by a wide margin. Kansas, however, went 31-5 and advanced to the Elite Eight, so that’s probably what Jackson had in mind when he took aim at Fultz.
